About George O'Brian Wyndham, 3rd Earl of Egremont

George O'Brien Wyndham, 3rd Earl of Egremont (18 December 1751 – 11 November 1837) was a British peer. A direct descendant of Sir John Wyndham, he succeeded to his father's titles in 1763 at the age of 12, inheriting estates at Petworth, Egremont, Leconfield and land in Wiltshire and Somerset. He later inherited the lands of the Earl of Thomond in Ireland. He was a great patron of art and interested in the latest scientific advances. He was an agriculturist, a friend of Arthur Young, and enthusiastic for canal building, investing in many commercial ventures for the improvement of his estates. He was also not entirely indifferent to politics.

For some time the painter Turner lived at his Sussex residence, Petworth House, and many painters including John Constable, C R Leslie, George Romney, the sculptor John Flaxman, and other talented artists received commissions from Egremont, who filled his house with valuable works of art. The earl was a sponsor of the Petworth Emigration Scheme intended to relieve rural poverty caused by overpopulation. Generous and hospitable, blunt and eccentric, the earl was in his day a very prominent figure in English society. Charles Greville says, he was "immensely rich and his munificence was equal to his wealth"; and again that "in his time Petworth was like a great inn".
